Initially, the plan called for a military uprising to start on May 25, the one-year anniversary of the
May Revolution. The military forces, under Fulgencio Yegros, were expected to march from Itapúa supported by garrisons in other towns, but negotiations of governor Velasco with Portuguese representatives from Brazil, hastened the uprising. In the evening of May 14, 1811 a military insurrection broke out in Asunción garrison. Plotters led by captain Pedro Juan Caballero went to the Governor's quarters located on the main square of Asunción, where they were greeted by second lieutenant
Mauricio José Troche, a supporter of the plot, who was on duty and in charge of the small garrison of 34 men from
Curuguaty. At midnight, ensign
Vicente Ignacio Iturbe presented himself to governor Velasco with demands from plotters led by Caballero, which could be summarized as follows: • "Surrender of the main square, all the weapons and keys to the
Cabildo." • "Governor Velasco stays in power, but as a part of three-man junta which should include two representatives appointed by the officers at the quarters." A group of officers and politicians, which included captain Pedro Juan Caballero, Fulgencio Yegros, Vicente Ignacio Iturbe, Mauricio Jose Troche,
Fernando de la Mora,
Juan Valeriano de Zeballos and
José Gaspar Rodríguez de Francia forced governor Velasco to agree on the creation of a three-man executive junta. As governor Bernardo de Velasco was reluctant to accept the conditions presented by the plotters, additional revolutionary troops came to the square and set up a battery of eight cannons in front of the government house in Asunción; ensign Vicente Ignacio Iturbe brought a new ultimatum, setting a short deadline for response. It was already early morning on 15 May 1811. As the town garrison assembled, Governor Velasco hoping to avoid bloodshed, came to the government house's door and said: "If this is because of authority, I give up the command
baton." This announcement was met with joy by the assembled crowd. The flag was raised and a
21-gun salute fired amidst the ringing of church bells (this day is marked as Paraguayan Independence Day). On May 17 a public proclamation informed the people that a ruling junta, consisting of governor Velasco, Gaspar Rodriguez de Francia and Spanish-born Army captain Juan Valeriano de Zeballos had been created. Fulgencio Yegros reached Asunción only on 21 May 1811. ==Path towards full independence==
